Mobile electric power generation for hydraulic fracturing of subsurface geological formations

A system for providing mobile electric power, the system comprising:

• a gas turbine generator trailer comprising:
• an inlet plenum for collecting air flow directed into the gas turbine generator trailer;
• an exhaust collector for moving exhaust air out of the gas turbine generator trailer;
• and
• a single gas turbine generator trailer frame mounting both the inlet plenum and the exhaust collector in alignment with a length of the gas turbine generator trailer;
• an inlet and exhaust trailer comprising:
• an air inlet filter housing for supplying the air flow to the gas turbine generator trailer;
• an exhaust stack for collecting the exhaust air discharged from the gas turbine generator trailer, wherein the exhaust stack is configured to be rotated between a horizontal position and a vertical position;
• and
• a single inlet and exhaust trailer frame mounting both the air inlet filter housing and the exhaust stack,
• wherein the gas turbine generator trailer and the inlet and exhaust trailer are separate and independently movable,
• wherein the gas turbine generator trailer and the inlet and exhaust trailer are both configured to be positioned parallel to each other along the length of the gas turbine generator trailer in an operational mode, and
• wherein in the operational mode the air inlet filter housing is connected to the inlet plenum and the exhaust stack is connected to the exhaust collector between facing sides of the gas turbine generator trailer and the inlet and exhaust trailer.

An apparatus for providing mobile electric power comprising:

• a power generation trailer configured to convert at least one type of hydrocarbon fuel to electricity, wherein the power generation trailer comprises an inlet plenum and an exhaust collector, wherein both the inlet plenum and the exhaust collector are aligned along a length of the power generation trailer and mounted to a single power generation trailer frame;
• and
• an inlet and exhaust trailer that moves independently relative to the power generation trailer in a transportation mode and comprises a single inlet and exhaust trailer frame, an air inlet filter housing and an exhaust stack, the air inlet filter housing and the exhaust stack both being mounted to the single inlet and exhaust trailer frame, wherein the exhaust stack is capable of being rotated between a horizontal position and a vertical position, wherein the inlet and exhaust trailer is configured to:
• couple to at least one vertical side of the power generation trailer, wherein the at least one vertical side is parallel to the length of the power generation trailer;
• provide air flow with the air inlet filter housing to the inlet plenum at the at least one vertical side of the power generation trailer;
• and
• direct exhaust air from the exhaust collector with the exhaust stack at the at least one vertical side of the power generation trailer.
